Examples with Isolation com.facebook.presto.sql.tree.Isolation used on opensource projects

Example 1 with Isolation

use of com.facebook.presto.sql.tree.Isolation in project presto by prestodb.

the class TestStartTransactionTask method testStartTransactionTooManyIsolationLevels.

@Test
public void testStartTransactionTooManyIsolationLevels() {
    Session session = sessionBuilder().setClientTransactionSupport().build();
    TransactionManager transactionManager = createTestTransactionManager();
    QueryStateMachine stateMachine = createQueryStateMachine("START TRANSACTION", session, true, transactionManager, executor, metadata);
    assertFalse(stateMachine.getSession().getTransactionId().isPresent());
    StartTransactionTask startTransactionTask = new StartTransactionTask();
    try {
        getFutureValue(startTransactionTask.execute(new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.READ_COMMITTED), new Isolation(Isolation.Level.READ_COMMITTED))), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
        fail();
    } catch (SemanticException e) {
        assertEquals(e.getCode(), INVALID_TRANSACTION_MODE);
    }
    assertTrue(transactionManager.getAllTransactionInfos().isEmpty());
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
}

Example 2 with Isolation

use of com.facebook.presto.sql.tree.Isolation in project presto by prestodb.

the class TestStartTransactionTask method testStartTransactionExplicitModes.

@Test
public void testStartTransactionExplicitModes() {
    Session session = sessionBuilder().setClientTransactionSupport().build();
    TransactionManager transactionManager = createTestTransactionManager();
    QueryStateMachine stateMachine = createQueryStateMachine("START TRANSACTION", session, true, transactionManager, executor, metadata);
    assertFalse(stateMachine.getSession().getTransactionId().isPresent());
    StartTransactionTask startTransactionTask = new StartTransactionTask();
    getFutureValue(startTransactionTask.execute(new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.SERIALIZABLE), new TransactionAccessMode(true))), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertTrue(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
    assertEquals(transactionManager.getAllTransactionInfos().size(), 1);
    TransactionInfo transactionInfo = transactionManager.getTransactionInfo(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().get());
    assertEquals(transactionInfo.getIsolationLevel(), IsolationLevel.SERIALIZABLE);
    assertTrue(transactionInfo.isReadOnly());
    assertFalse(transactionInfo.isAutoCommitContext());
}

Example 3 with Isolation

use of com.facebook.presto.sql.tree.Isolation in project presto by prestodb.

the class TestSqlParser method testStartTransaction.

@Test
public void testStartTransaction() {
    assertStatement("START TRANSACTION", new StartTransaction(ImmutableList.of()));
    assertStatement("START TRANSACTION ISOLATION LEVEL READ UNCOMMITTED", new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.READ_UNCOMMITTED))));
    assertStatement("START TRANSACTION ISOLATION LEVEL READ COMMITTED", new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.READ_COMMITTED))));
    assertStatement("START TRANSACTION ISOLATION LEVEL REPEATABLE READ", new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.REPEATABLE_READ))));
    assertStatement("START TRANSACTION ISOLATION LEVEL SERIALIZABLE", new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.SERIALIZABLE))));
    assertStatement("START TRANSACTION READ ONLY", new StartTransaction(ImmutableList.of(new TransactionAccessMode(true))));
    assertStatement("START TRANSACTION READ WRITE", new StartTransaction(ImmutableList.of(new TransactionAccessMode(false))));
    assertStatement("START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ ONLY", new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.READ_COMMITTED), new TransactionAccessMode(true))));
    assertStatement("START TRANSACTION READ ONLY, ISOLATION LEVEL READ COMMITTED", new StartTransaction(ImmutableList.of(new TransactionAccessMode(true), new Isolation(Isolation.Level.READ_COMMITTED))));
    assertStatement("START TRANSACTION READ WRITE, ISOLATION LEVEL SERIALIZABLE", new StartTransaction(ImmutableList.of(new TransactionAccessMode(false), new Isolation(Isolation.Level.SERIALIZABLE))));
